SPECIFICATION forming part of Letters Patent N o. 613,727, datedNovember 8,1898. j

Application filed October 25, 1897. Serial No. 656,304. (No model.)

To a/ZZ whom t may concern.-

Beit known that I, KELLY NEWTON SHARP, a citizen of the United States,residing at Harmony Grove, in the county of Jackson and State ofGeorgia, have invented a new and useful Plow, of which the following isa specification.

This invention relates to plows in which the beam is made reversible, soas to bring either a right or a left hand plow in Working position, alarge or a small plow, or a plow or a cultivator shovel into position,according to the condition of the soil or the nature of the work to beperformed.

The purpose of the improvement is to provide simple and effective meansfor connecting the parts of the beam, whereby the front portion bearin gthe earth-treating devices can be turned so as to bring either size orstyle of shovel or plow into active operation, and whereby the parts aresecured firmly in the adjusted position anda stout joint is-had betweenthem.

For a full understanding of the merits and advantages of the inventionreference is to be had to the accompanying drawings and thek followingdescription.

The improvement is susceptible of various changes in the form,proportion, and the minor details of construction without departing fromthe principle or sacrificing any of the advantages thereof, and to afull disclosure of the invention an adaptation thereof is shown in theaccompanying drawings, in which- Figure 1 is a side elevation of a plow,showing the application of the invention, the shovels being omitted. pFig. 2 is a top plan View of the inner portion of the plow-beam. Fig. 3is a vertical longitudinal section of the contiguous end portions of thebeam-sections. Fig. 4t is a horizontal section thereof. Fig. 5 is adetail view in perspective of the front plate. Fig. 6 is a detail viewin perspective of the rear plate.

Corresponding and like parts are referred to in the followingdescription and indicated in the several views of the drawings Vby thesame reference characters.

The beam is composed of a rear part or section 1 and a front part orsection 2, which is rotatable relatively to the rear part, which latteris fixed and carries the handles 3. The

clevis 4 is applied to the front end of theroa tatable part 2, andconsists of a `strap having its end portions embracing the top andvbottom sides of the beam and secured thereto, and an intermediatebearing 5', having its rear end entering an opening in the end ofy thebeam and providing loops or eyes a, to either one of which the draft maybe applied, according to the required pitch to be given to theplow-point. nection with the bearing 5 to admit of the front part of thebeam turning without twisting the traces to which the singletree isattached and which is coupled to the' said eyebolt. The standards 7 areof like formation and are adapted to receive the onea righthand and theother a left-hand plow or plows of different styles and sizes, or a plowand a cultivator, whereby upon turning'the front part of the beam eitherone of the two earthtreating devices may be brought into position foractive service. The beam ends of the standards incline forwardly, asshown at and cross, the outer ends being odset, as shown at 9, to clearthe inner ends and admit of the standards being'adjusted to give theproper pitch to the shovels or plow-points. Each standard is composed ofcorresponding side members of like formation, and the corresponding sidemembers are clamped against the opposite sides of the beam by boltspassing through transversely-alining openings in the overlapping endportions upon opposite sides of the point of crossing.

Circular plates or disks 10 and 11 are secured to the contiguous ends ofthe beamsections 1 and 2 in the following manner: The front plate ofdisk 10 is formed with parallel flanges 12, which embrace the sides ofthe front part 2 and are secured thereto by bolts passing through pairsof openings formed in the flanges and in transverse alinement. A journal14 is formed centrally on the rear face or side of the plate and has anopening through which passes a bolt 15, by means of which the two platesare connected. Notches 16 are formed in the upper and lower edges of theplate 10 and coperate with a spring-catch 17 to hold the beam-section 2in an adjusted po-V sition. The rear plate 11 has parallel flanges 18 onits rear side, which embrace the sides of the fixed section 1 and arebolted thereto.

An eyebolt 6 has swivel con- ICO These iianges are connected at theirupper ends by a transverse flange 19,-which overlaps the top side of thepart 1, and this flange has a longitudinal groove 2O in its upper sideto receive the front portion of the catch 17 and brace it laterally. Theside flanges 18 are connected intermediate of their ends by a fillingwhich is centrally bored to receive the journal 14 and form a bearing 21therefor. The bore of the bearing 21 and the journal 14 are of taperingform, whereby a snug joint is secured to prevent lost motion. A loop orapertured extension 22 is formed at the upper edge of the plate 1l aboutin line with the space formed between the fianges 18 and directly inline with the longitudinal groove and receives the front end of thecatch 17. The bolt 15 for connecting the two plates passes through thejournal 14, and the head or nut at its rear end is of a size to overlapthe rear end of the bearing 21, so as to hold the two plates together.It will be understood that the plates are coupled prior to attachingthem to the respective parts of the beam.

The catch 17, which is a stout flat spring,

is secured at its rear end to the part 1, and its front end operatesthrough the loop 22 and is adaptedto enter one of the notches 16, so asto hold the parts 1 and 2 in position. A wire 23 or like connection issecured to the front end of the catch 17 and extends within convenientreach, so as to be pulled upon for releasing the catch when it isdesired to turn the part 2 for bringing one or the other oftheearth-treating devices into working position. The upper end of thewire is secured to the top cross-bar of the handles and is sufficientlyslack to bulge, so as to be grasped by the attendant.

The bolt l5 and journal 14 are supplemented in their action by hooks 24,which project beyond the front face of the rear plate 11 and embrace theedge portion of the front plate 10. These hooks are provided in upperand lower pairs and are disposed to come upon opposite sides of thenotches 16. As is ob'- vious, the hooks 24 serve to hold the plates 10and 11 together and guide them materially in their relative turning andpreclude any binding -action between the journal 14 and its bearing 21.

Having thus described the invention, what is claimed as new is- 1. In areversible plow, a divided beam having alined sections, opposing platesrigidly fitted to the contiguous ends of the beamsections and iiatlyabutting, one of said plates being provided with a central bearing, andthe other plate having projected therefrom a central journal registeringin said bearing, a separate fastening for holding the two platestogether in pivotal relation, and a locking device for thebeam-sections, substantially as set forth.

2. In areversible plow, a divided beam having alined sections, opposingflatly-abutting plates fitted to the contiguous ends of thebeam-sections, and both provided at one side with ostanding flangesembracing such sections, one of said plates being provided withperipheral notches, and the other plate having an enlon gated groove anda loop spanning the same, a central pivotal connection for the twoplates, and a catch operating within the said elongated groove beneaththe loop and adapted to engage the peripheral notches in one of theplates, substantially as set forth.

3. In a reversible plow, a divided beam having alined sections, opposingplates rigidly fitted to the contiguous ends of the beam-sections andflatly abutting, one of said plates being provided with a central offsetbearing seated in one of the beam-sections and having a tapered bore,and the other plate having projecting from one side thereof a centraltapered journal registering in the tapered bore of said bearing, a boltpassing through the journal and holding the two plates together inpivotal relation, and a locking device for the beam-sections,substantially as setforth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

KELLY NEWTON SHARP.
